' 4 claims. (o1. ,2a-.68)

My invention relates to va tensioned weather strip and the principal object of the invention. is to provide means for adjusting tension for Varying the tension on the weather strip.

Another object of the invention is to provide means for adjusting the tension on the Weather strip, which means is accessibleA when the weather strip is in its operative position.`

This invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the.l following description. However, the drawingmerely shows and the following description merely describes an' embodiment ofthe present'invention, which is given by way of illustration or example only.

Reference is hereby made to my ccb-pending application Serial No. 285,973, led July 22, 1939, on Weather stripping, for matter shown and described but not claimed herein.

In the drawing, like reference characters designate similar parts in the several views.

Figure 4 is an enlarged, longitudinal, broken section of a corner of a sash to which an embodiment of my present invention has been applied.

Figure 5 is a section taken on the line 5`5 of Figure 4.

Figure 6 is a broken, perspective view of a detail.

Figure 7 is a broken elevation of a detail.

Referring more in detail to the drawing, the reference numeral 6 generally designates a Window frame in which sashes 1 and 8 are slidably hung. The jambs of the window frame are shown at 9. Window glass I is held by putty I2 in the stiles I3 and rails I4 of each sash.

The stiles are routed and are provided with different sizes and shapes of aligned bores. The first bored section I is cylindrical and provides a bearing for a pin I6 that is cross slotted at one end I1, as best shown in Figure 6, and is threaded at the other end, as shown at I8. A circular, integral shoulder I9 is fastened on the pin I6 in an enlarged, square bore 20.

A nut 2| having a square periphery i'lts in the bore 20. The stile I3 is routed longitudinally at its outer edge, as shown at 22, anda weather strip 23 is disposed lo-ngitudinally in the rout 22. The

depthvof the rout 22 is substantially the same as the depth of the strip.` 23. A coil spring 24 is arranged inthe bored portion 20 between the nut 2| and the rear face ofthe weather strip 23.

The jamb '9. has an angular recess 25 and the weather strip 23 has an angular, ridge-like projection 26 that projects into the recess 25. The angle of the projection 2B is preferably a narrovverl angle than that of the recess 25.

Metal plates 21 are bolted at'the'ends of the Stiles, to close the ends of the longitudinal routs 22, thereby preventing longitudinal.displacement of the weather strips 23 during movement ofi the window sash.

The bore I5 is kcountersunk at'the opposite end from the weather strip, toI receive a bottomless cupr 28. Prongs29 provided by the cross slotted end |'I of the pin |6are swaged outward against' the inner' face of the cup 28, as perhaps best shown in Figure '7. The cup 23 is thereby held in position and the pin I6A is held against movement to the right in Figures .2 and 4. The shoulder I9 abutting against the end of the bore 2G prevents movement. of the pin ||v to thel left in Figures 2 and 4.

The notched end of the vpin I6 provides two notches 30 and 3|-`at right angles to each other. 'Ihe notch 3| is the deeper of the two notches. When the end |'I of the pin I6 is arranged in the cup 28, prongs 32, 33, 34 and 35 are swaged outwardly. The swaging is effected substantially to the depth of the shallower notch 3U. This leaves the notch 3| for the reception of a screw-driver. In Figure 2 the deeper notch 3| is shown in elevation, and in Figure 4 the notch 30 is shown in elevation. In the latter View, the deeper notch 32 is shown by a broken line. The cross arrangement and the relative depth of the notches is best shown in Figure 6.

To adjust the tension of the springs 21| behind the Weather strips 23, a screw-driver is applied to the notched end I'I of the pin I6. Turning the pinv I6 causes the nut 2| tomove one way or another, depending upon the direction of rotation of the pin I6. The tension on the springs 24 is increased or decreased, depending upon whether the nuts 2`| are moved to `or from the weather strips 23. Thus it can be seen that the tension of the weather strips may be varied even though the sashes and weather strips are in their operative positions.

This invention is especially of value when assembling sashes in frames in new construction, or when reassembling is done by reason oi repair or reconstruction. In any of these events, the

ing whether the springs bearing against theV weather strips cause the sashes to be rmly held in adjusted positions and yet permit the sashes to be moved to different effort. The present invention is also of value in taking up wear on the weather strips, after they have been used for a considerable period.

positions without undueV While I have illustrated and described what IV now regard as the preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular form of construction illustrated and described, but desire to avail myself of all modifications which may fall within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In combination with closure elements, a

weather strip movably supported on o-ne of said elements to bear against the other element, spring means disposed with one end freely engaging the strip and tending to urge the strip into such bearing position, a threaded pin rotatable through a portion of said element, a threaded abutment arranged on the pin and engaging the other end of the spring to adjust the tension on the spring, means to prevent turning movemen't of the abutment with the pin, a shoulder on the pin engaging one side of the said p ortionY of the element to prevent lengthwise movement of the pin out of position under action of the spring, and the pin having an adjusting head opposed to the shoulder and engaging the opposite side of the said portion of the element to prevent movement of the pin in the opposite direction, the adjusting head being accessible exteriorly of the supporting element in use.

2. A weather strip, a supporting element with respectl to which said strip is movable, spring means disposed with one end freely, yieldingly engaging the strip and tending to urge the strip outwardly of said element, a threaded pin rotatably supported against lengthwise movement in said element, a threaded abutment arranged on the pin and engaging the other end of the spring to adjust the tension on the spring, means to prevent turning movement of the abutment with the pin, the pin having an outer slotted end and having outwardly swaged portions between its slots to limit longitudinal movement of the pin in one direction.

3. A weather strip, a support on which said strip is movable to an outer bearing position, spring means tending 'to urge the strip into such bearing position, a threaded pin, a threaded abutment arranged on the pin to adjust the tension on the spring, and the pin having its outer end cross slotted, the slots being of different depths, also having outwardly swaged prongs at the end thereof between the cross slots, inclined with respect thereto substantially to the depth of the shallower slot.

4. A window sash having a -groove and a bore at right angles to the groove, a weather strip slidable in said groove for movement outwardly of the sash, a threaded pin having rotatable bearing through a portion of the sash and extending at its inner end axially of, and within, the sash bore, a follower and slidable and non-rotatable in said bore, a spring compressed between the follower and the weather strip with its outer end freely engaging the strip for constantly applying its tension against the latter, means holding the pin against lengthwise movement in the pin bearing portion of the sash including a cross-slotted head at the outer exposed end of the pin having swaged extensions between the slots, and a conical thimble in a surface of the pin bearing portion of the sash and in which the said swaged end of Vthe pin is movably seated.
